Phenotypic characterization of MDR E. coli and P. aeruginosa

Isolates	LF/NLF	Oxidase	Indole	Citrate	TSI
					Slant	Butt	Gas
M032	NLF	Yes	No	Yes	Red	Yellow	No
M034	NLF	Yes	No	Yes	Red	Orange red	No
M064	NLF	Yes	No	Yes	Red	Orange red	No
M066(1)	NLF	Yes	No	Yes	Red	Orange red	No
M066(2)	NLF	Yes	No	Yes	Red	Yellow	No
PA-27853	NLF	Yes	No	Yes	Red	Orange red	No
M103	LF	No	Yes	No	Yellow	Yellow	No
M165	LF	No	Yes	No	Yellow	Yellow	Yes
EC-25922	LF	No	Yes	No	Yellow	Yellow	Yes

Keys: NLF Non lactose fermenter, LF Lactose fermenter. Yes = Positive for that test

No = Negative for that test, M103 and M165 = E. coli isolates

M032, M034,M064, M066(1) and M066(2) = P. aeruginosa isolates

PA-27853 and EC-25922 = ATCC strains of P. aeruginosa and E. coli respectively

Red/Yellow (Slant/Butt) = Indication of dextrose fermentation only

Red/Orange red (Slant/Butt) = Absence of carbohydrate fermentation

Yellow/Yellow (Slant/Butt) = Indication of fermentation of dextrose, lactose and/or sucrose
